How long will the pain from uterine contractions last after balloon insertion?

Generally, after the insertion of a balloon catheter, continuous uterine contraction pain may last for about 10 hours.

Prior to labor, a balloon catheter is inserted to accelerate the frequency of uterine contractions and achieve the purpose of labor induction. Since oxytocin is often administered under medical supervision during induction, the balloon catheter usually needs to remain in place for more than 10 hours. If contractions become regular in frequency and intensity during this period, the woman will generally experience pain throughout the entire 10-hour duration. If contractions are irregular in frequency or intensity, the pain may last even longer and feel more severe.

It is recommended that pregnant women try to stay emotionally calm and avoid excessive tension after balloon insertion, as anxiety may lead to irregular contractions. Additionally, remaining in a supine (flat on the back) position for a short time after insertion helps the balloon function effectively. Moreover, it's best not to reuse a balloon catheter after a single use to prevent bacterial infection, which could interfere with the induction process.
